Although national rates remained stable or increased slightly, the overall Apache suicide death rates dropped following the suicide prevention program. The community surveillance system served a critical role in providing a foundation for prevention programming and evaluation.
Objectives. We examined suicide and suicide attempt rates, patterns, and risk factors among White Mountain Apache youths (aged < 25 years) from 2001 to 2006 as the first phase of a community-based participatory research process to design and evaluate suicide prevention interventions. Methods. Apache paraprofessionals gathered data as part of a tribally mandated suicide surveillance system. We compared findings to other North American populations. Results. Between 2001 and 2006, 61% of Apache suicides occurred among youths younger than 25 years. Annual rates among those aged 15 to 24 years were highest: 128.5 per 100 000, 13 times the US all-races rate and 7 times the American Indian and Alaska Native rate. The annual suicide attempt incidence rate in this age group was 3.5%. The male-to-female ratio was 5:1 for suicide and approximately 1:1 for suicide attempts. Hanging was the most common suicide method, and third most common attempt method. The most frequently cited attempt precipitants were family or intimate partner conflict. Conclusions. An innovative tribal surveillance system identified high suicide and attempt rates and unique patterns and risk factors of suicidal behavior among Apache youths. Findings are guiding targeted suicide prevention programs.
The National Strategy for Suicide Prevention highlights the importance of improving the timeliness, usefulness, and quality of national suicide surveillance systems, and expanding local capacity to collect relevant data. This article describes the background, methods, process data, and implications from the first-of-its-kind community-based surveillance system for suicidal and self-injurious behavior developed by the White Mountain Apache Tribe with assistance from Johns Hopkins University. The system enables local, detailed, and real-time data collection beyond clinical settings, with in-person follow-up to facilitate connections to care. Total reporting and the proportion of individuals seeking treatment have increased over time, suggesting that this innovative surveillance system is feasible, useful, and serves as a model for other communities and the field of suicide prevention.
Identifying the transmission sources and reservoirs of Streptococcus
pneumoniae (SP) is a long-standing question for pneumococcal epidemiology,
transmission dynamics, and vaccine policy. Here we use serotype to identify SP
transmission and examine acquisitions (in the same household, local community, and county,
or of unidentified origin) in a longitudinal cohort of children and adults from the Navajo
Nation and the White Mountain Apache American Indian Tribes. We found that adults acquire
SP relatively more in the household than other age groups, and children 2–8 years old
typically acquire in their own or surrounding communities. Age-specific transmission
probability matrices show that transmissions within household were mostly seen from older
to younger siblings. Outside the household, children most often transmit to other children
in the same age group, showing age-assortative mixing behavior. We find toddlers and older
children to be most involved in SP transmission and acquisition, indicating their role as
key drivers of SP epidemiology. Although infants have high carriage prevalence, they do
not play a central role in transmission of SP compared with toddlers and older children.
Our results are relevant to inform alternative pneumococcal conjugate vaccine dosing
strategies and analytic efforts to inform optimization of vaccine programs, as well as
assessing the transmission dynamics of pathogens transmitted by close contact in
general.
American Indian adolescents are at disproportionate risk for suicide, and community-based studies of this population, which allow a deeper understanding of risks and resilience to inform interventions, are rare. This is a cross-sectional study of N = 71 Apache adolescents. Strengths include the role of the community and American Indian paraprofessionals in the design, implementation, and interpretation of findings. Participants were M = 16.0 years old, 65% female, and 69% multiple attempters. Risks included suicidal behavior among peers and family (68%), caregivers with substance problems (62%), and participant substance use history, namely alcohol (91%) and marijuana (88%). Areas of resiliency included lower depression scores (M = 23.1) and cultural activity participation. A multi-tiered intervention at individual, family, and community levels is needed.
